    All Methods Instance Methods Concrete Methods
    Modifier and Type | Method and Description
    --- | ---
    `void` | `configure(ChannelPipeline pipeline)` This method is called from within `AbstractChannelizer.initChannel(SocketChannel)` just after the SSL handler is put in the pipeline.
    `Object` | `createIdleDetectionMessage()` Create a message to send to seemingly dead clients to see if they respond back.
    `void` | `finalize(ChannelPipeline pipeline)` This method is called after the pipeline is completely configured.
    `UnifiedHandler` | `getUnifiedHandler()`
    `void` | `init(ServerGremlinExecutor serverGremlinExecutor)` This method is called just after the `Channelizer` is initialized.
    `boolean` | `supportsIdleMonitor()` Determines if the channelizer supports a method for keeping the connection alive and auto-closing zombie channels.

    - #### init

          public void init(ServerGremlinExecutor serverGremlinExecutor)

      Description copied from interface: `Channelizer`
      This method is called just after the `Channelizer` is initialized.
      Specified by:
        `init` in interface `Channelizer`
      Overrides:
        `init` in class `AbstractChannelizer`

    - #### configure

          public void configure(ChannelPipeline pipeline)

      Description copied from class: `AbstractChannelizer`
      This method is called from within `AbstractChannelizer.initChannel(SocketChannel)` just after the SSL handler is put in the pipeline. Modify the pipeline as needed here.
      Specified by:
        `configure` in class `AbstractChannelizer`

    - #### finalize

          public void finalize(ChannelPipeline pipeline)

      Description copied from class: `AbstractChannelizer`
      This method is called after the pipeline is completely configured. It can be overridden to make any final changes to the pipeline before it goes into use.
      Overrides:
        `finalize` in class `AbstractChannelizer`

    - #### getUnifiedHandler

          public UnifiedHandler getUnifiedHandler()

    - #### supportsIdleMonitor

          public boolean supportsIdleMonitor()

      Description copied from interface: `Channelizer`
      Determines if the channelizer supports a method for keeping the connection alive and auto-closing zombie channels.

    - #### createIdleDetectionMessage

          public Object createIdleDetectionMessage()

      Description copied from interface: `Channelizer`
      Create a message to send to seemingly dead clients to see if they respond back. The message sent will be dependent on the implementation. For example, a websocket implementation would create a "ping" message. This method will only be used if `Channelizer.supportsIdleMonitor()` is `true`.
